Real octane boost. Real MMT.

Rislone Hy-per Fuel Octane Booster increases your fuel’s octane rating to stop engine hesitation, knock and ping while also increasing power and performance. The formula works equally well on classic muscle cars, newer, smaller, harder-working engines, and off-road and racing applications. The increased octane allows the engine to run at optimum spark timing, which not only creates more power but also, in many engines, reduces emissions and increases fuel mileage. It’s also the best insurance against bad gas you can find. If you’re all about high performance, then you know your car relies on octane for top performance. Our Rislone Super Concentrated Octane Booster does just that.
